Chemical Hazards - JLG 642 Operation & Safety Manual

Section 1—General Safety Practices

Chemical Hazards

• DO NOT operate machine in an enclosed area without proper ventilation.
• DO NOT operate the machine in hazardous environments unless approved for that
purpose by JLG and site owner. Sparks from the electrical system and the engine
exhaust can cause an explosion.
• DO NOT fill the fuel tank or service the fuel system near an open flame, sparks or
smoking materials. Engine fuel is flammable and can cause a fire and/or explosion.
• DO NOT attempt to repair or tighten any hydraulic hoses or fittings while the engine is
running or when the hydraulic system is under pressure.
• Stop engine and relieve trapped pressure. Fluid in the hydraulic system is under
enough pressure that it can penetrate the skin.
• DO NOT use your hand to check for leaks. Use a piece of cardboard or paper to search
for leaks. Wear gloves to protect hands from spraying fluid.
